Since it seems like about half of the population prefers Coke and the other half prefers Pepsi, it is too bad the airlines and other places are only able to offer one brand due to their marketing agreements. I wonder how much NW/Delta receives from Coke to exclusively offer their products? Is it just free soda or are there other benefits for NW/Delta as well?

I prefer diet Pepsi and Mountain Dew so this really isn't the best news for me!
